Compile-time pre-calculations in C++ With C++17’s constexpr functions and C++20’s consteval specifier, it is easy to do io-independent pre-calculations of algorithms while compiling the program. This may not be useful or even possible in long running programs and is unlikely to make a difference in their performance, but in binaries that do short calculations with a set of parameters fixed at comp
Before you start implementing your custom concepts, it’s good to review some goodies in the Standard Library. There’s a high chance that there’s already a predefined concept for you. Today let’s have a look at concepts related to callable objects. Where to find them You can find most of the predefined concepts in the <concepts> header. Here’s a good list available at cppreference - Concepts librar
